3 NEO CAUTION: For safety reasons, please read the precautionary information Located at the end of this manual, before attempting installation 1.0 General The KOBOLD EchoKing level transmitter operates on the ultrasonic principle. An ultrasonic sound wave is pulsed eight times per second from the base of the transducer. The sound wave reflects against the process medium below and returns to the transducer. The microprocessor based electronics measure the time of flight between the sound generation and receipt, and translates this figure into the distance between the transmitter and process medium below. This design results in a high degree of accuracy with no requirement for contact with the fluid. 2.0 Specifications : 0.5 to 24.5 feet Accuracy: ± 0.25% of span (air) Resolution: 0.125" (3 mm) Pulse Frequency: 50 khz Pulse Rate: 8 pulses per second Dead Band: 6" from transducer face minimum Display Type: 4 segment LED Display Units: Selectable Inch or cm Calibration/programming: Push button Fail-safe diagnostics: Relay reverts to safe position Temperature rating: -4 to 140 F; (-20 to 60 C) Temp. compensation: Automatic over entire range Pressure rating: C., psi per C above 25 C.

5 3 NEO 3.0 Installation 3.1 Mechanical Installation Mounting the NEO properly is critical to operation. To install the NEO ultrasonic level transmitter in a system proceed as follows: If the NEO is installed such that the transducer face is recessed in a fitting or flange rather than flush with the tank lid, follow the criteria listed in Diagram 3.1 below. For a recess I.D. less than 3", do not recess the NEO more than 1 for best results. Diagram 3.1 Recess installation Recess I.D. (inches) Max. Depth (inches)

6 NEO The NEO level transmitter must be installed to avoid interference of the ultrasonic beam cone from the tank side wall. It must be installed such that the beam cone is not interfered by obstructions in the tank such as pipes, nozzles, ladders etc. The transmitter cannot be mounted at an angle (i.e. must be mounted perpendicular to the fluid surface). The NEO will not function in a vacuum. Diagram 3.2 illustrates these mounting precautions. Diagram 6.2 on page 11 gives the beam cone radius for various distances from the transducer face. Diagram 3.2 Installation Precautions Avoid Interference from tank side-wall Do not install at an angle Avoid interference from obstructions NEO will not operate in a vacuum

7 5 NEO 3.2 Special Instructions for Mounting near Tank Sidewall, Obstructions, and Turbulent Tanks When installing the NEO EchoKing level transmitter, every effort should be made to install the unit adhering to the precautions detailed in section 3.1.2, on page 4. In some installations where it is impossible to install away from the tank sidewall, away from obstructions or where the tank has a turbulent fluid surface it still may be possible to use the NEO level transmitter by attaching a two inch nominal I.D. pipe to the NEO transducer. The ultrasonic beam is then directed down the length of the pipe to the fluid surface and back to the transducer face. For this type of installation to work successfully, the following specific installation requirements must be met: The fluid cannot be a coating type media which will coat the inside of the pipe. If this occurs, the ultrasonic signal will be dispersed and the signal reflected off the fluid surface will not be strong enough to be detected by the NEO. The pipe used must be a single, continuous, straight length with no fittings, couplings or discontinuities except for the fitting which attaches the pipe to the 2 inch NPT fitting on the NEO transducer face. The pipe must extend into the tank the entire desired measuring length. A vent hole must be placed in the pipe. Both the vent hole and the two inch NPT fitting which attaches the pipe to the NEO must be placed within the six inch deadband which extends from the transducer face. If they extend beyond this deadband, they will interfere with the transmitted signal. Diagram 3.3 Illustrates this special installation. Diagram 3.3.Special NEO EchoKing Installation Pipe fitting and vent hole must be placed within 6 from the transducer face 6 Xducer deadband The pipe must be continuous and extend the entire tank measuring length

8 NEO Electrical Connections The NEO-5000 series level transmitter has both a 4-20 ma continuous level transmitter and SPDT relay. The SPDT relay can be programmed as a level alarm, as a pump-up/ pump-down control, to alarm when the transmitted ultrasonic signal return is lost, or to alarm when the 4-20 ma signal is lost. Diagram 4.1 shows the wiring color coding for the NEO. The NEO requires a VDC power with at least a 200 ma supply. Diagram 4.1 NEO-5000 Wiring ma Transmitter Wiring The NEO-5000 Series level transmitter has two different types of 4-20 ma transmitters. The Model NEO-5003 is a current sourcing 4-20 ma transmitter. This means that it has an internal power source for the 4-20 ma loop and requires no external D.C. power for the 4-20 ma current loop. It is for use with un-powered 4-20 ma loops and with PLCs which have no power source at their current inputs (current sinking inputs). The Model NEO-5004 is a current sinking 4-20 ma transmitter which requires an external power source in its 4-20 ma loop. It is for use with 4-20 ma loops in which has a power source in the loop and with PLCs which have a power source at their current inputs (current sourcing inputs). Diagram 4.2 shows wiring to a 4-20 ma loop. Diagram 4.3 shows wiring to PLCs.

10 NEO Programming/Calibration EchoKing Holding down the MENU key will scroll the display through its programming sequence. The display is lit only during the programming mode. It will automatically extinguish when programming is completed and the push-buttons are idle for 30 seconds. The following is a description of each item in the programming sequence: Program current settings: First determine the 4mA and 20 ma distances for the NEO. The 4mA setting is labeled EC4 and the 20 ma setting is labeled EC20. These settings represent the distance from the 4mA and 20 ma level to the bottom of the sensor. The EC4 value will be larger than the EC20 value. EC4: Hold the [MENU] key until EC4 appears in the display. Release the key and wait until a value appears. This value is the level that the NEO currently senses. If this is an acceptable 4 ma tank level, press [SET] to lock the value as the new EC4. If not, press either the [ ] or [ ] keys and the old setting for the EC4 will appear. From here, use the [ ] or [ ] keys to raise or lower the value to the correct measurement. Press the [SET] key to lock this value as the new EC4 value. EC20: Hold the [MENU] key until EC20 appears in the display. Release the key and wait until a value appears. This value is the level that the NEO currently senses. If this is an acceptable 20 ma tank level, press [SET] to lock the value as the new EC20. If not, press either the [ ] or [ ] keys and the old setting for the EC20 will appear. From here, use the [ ] or [of] keys to raise or lower the value to the correct measurement. Press the [SET] key to lock this value as the new EC20 value. RLAY: Only an indicator for the next two modes. The 10 amp relay is latched between the HSET and LSET points (for pump-up/pump-down as an example). To simply energize or de-energize the relay at a single level (as for a level alarm), HSET and LSET should be set to the same value. HSET & LSET: Sets the high point and low point for relay activation. Press [MENU] key until either HSET or LSET appears. Wait for the display to change to the current value and press either [ ] or [ ] to change the numeric value. The [SET] key does not need to be pressed to lock in the value. Repeat process for the other setting.

11 9 NEO SAF1/SAF2: The 10 amp relay inside the NEO can be used in a fail-safe design for your system. When [SAF1] is set, the relay will de-energize when the acoustic return signal is LOST. When [SAF2] is set, the relay will energize when the 4-20 ma signal is LOST. Response times will vary according to the setting of the NEO ([FAST] or [SLOW] modes). FAST/SLOW: [FAST] is the standard in which the NEO operates. [SLOW] is designed to dampen out turbulence in tanks. In the [FAST] mode, the NEO will average 8 responses per second and update every second. In the [SLOW] mode, the NEO will average over the preceding 10 seconds. When used with [SAFI] or [SAF2], the time for the relay to switch over is 30 seconds for the [FAST] mode, and 2.5 minutes for the [SLOW] mode. ALIN: Indicates that the unit is in the Alignment Mode. Display will show the return signal strength in db's. Used as an indicator for mechanical alignment of the NEO and/or to indicate signal attenuation. Typical readings range between 0 and 50 db's. For optimum alignment, first energize the unit and receive a valid return signal. Then select the ALIN mode and adjust the NEO until the display is maximized. ON/OFF: Used to toggle alignment [ON] or [OFF] with the [Set] key. The ALIN mode must be turned [OFF] when alignment is completed. This mode will not automatically default back to [LEVL]. TANK: Used as an indication for [TANK]. TANK sets the maximum tank depth that the NEO will recognize. It will filter out any returns greater than the tank value. This feature is useful for eliminating false readings in tanks which have irregular shaped bottoms or obstructions near the bottom of the tank. When the signal does exceed the tank value, the tank value will be displayed and transmitted. Use the next setting to change the TANK value. (value): Use the [ ] and [ ] buttons to change the current TANK value and press [SET] to enter the value. The NEO will limit the displayed and transmitted level to this distance. The maximum distance is 300 inches.

12 NEO Troubleshooting 6.1 Maximum Application for the NEO Level Transmitter The maximum range of the NEO is 24.5 feet at 110 db. Yet a number of factors can reduce the overall quality of signal return and shorten the accurate range of the transmitter. To determine the maximum application range of the product, follow the example signal return formula against the echo attenuation graph below. Diagram 6.1 Echo Attenuation Graph

13 11 NEO 6.2 Loss of Acoustic Return Signal A reading of LOST in the display of the NEO indicates the NEO is not receiving a valid return signal. In addition to a LOST appearing on the NEO display, the transmitter output will freeze at the last value where a valid acoustic return was received regardless of changes in tank level. If LOST appears, please check for: Interference such as the side wall, ladders, seams, rungs or pipes within the NEO's beam cone. The beam cone data is listed in Diagram 6.2 below. Proper installation such that the NEO is installed level and free from interference from the installation fitting. Sufficient power being supplied to the NEO. The NEO requires 14 to 36 VDC power with a minimum supply of 200 ma. Proper programming of the TANK function. For best results, set the TANK function as the distance from the bottom of the tank to the transmitter. When the acoustic return is again recognized by the NEO. The LOST display will clear and the transmitter will resume normal function. Diagram 6.2 NEO Beam Cone Data (feet) Radius (inches) (feet) Radius (inches)

14 NEO Factory Settings The NEO sensor is preset at the factory. When powering up the sensor the first time, the factory settings will be active. If at any time in you need to return to these settings, remove power from the sensor and wait 10 seconds. Press the [Set] and [Menu] buttons simultaneously while powering up the sensor. Table 6.1 Factory Calibration Default Values LEVL Inches SAF1/2 SAF1 EC 4 8 F/S FAST EC ALIN N/A RLAY N/A OFF OFF HSET 5 TANK N/A LSET 288 value Changing the Display Units The NEO comes preset to measure in inches. To change the unit to display centimeters, remove power to the unit and wait 10 seconds. Press [ ] and [Set] simultaneously while powering up the sensor. The NEO will now read in centimeters. To return to inches, remove power and wait 10 seconds. Press [ ] and [Set] simultaneously while powering up the sensor. 6.5 If the Transmitter Output Current is Always 4 ma or 20 ma If the output of the NEO is always reading 4mA or 20 ma, check the EC 4 and EC 20 input values for the NEO. The display of the NEO reads to the 1/10 of an inch or cm. A display of 1234 is 123.4" and not 1234". 7.0 Maintenance The Series NEO level transmitter is an electronic device with no moving parts. It has a totally digital electronic design which means that there is minimal calibration drift. These features make the NEO virtually maintenance free. If a coating of process media should form on the sensor face the unit should be removed from the system and the sensor face cleaned. 8.0 Arrival of Damaged Equipment Your instrument was inspected prior to shipment and found to be defect-free. If damage is visible on the unit, we advise that you carefully inspect the packing in which it was delivered. If damage is visible, notify your local carrier at once.

Make a Fail-Safe System: Design a fail-safe system that accommodates the possibility of transmitter or power failure. In critical applications, KOBOLD recommends the use of redundant backup systems and alarms in addition to the primary system. Warning The NEO-50_1 is a loop powered device. The load should never exceed 900 Ohms. NEO-50_1-IS must be installed in accordance with drawing LU20CD rev B (see steps) for safe operation in a hazardous area. When installing the NEO-50_1, never tighten the transmitter from the body. Always use the wrench flat located above the threads. DEFINITION Step Three EC4 EC20 20 ma 4 ma EC4: The 4 ma setting for the NEO-50_1. The EC4 is the distance from the bottom of the NEO- 50_1 to the 4 ma set point. This setting is measured in either inches or centimeters on the display. The EC4 setting is typically greater that the EC20 setting. EC20: The 20 ma setting for the NEO-50_1. The EC20 is the distance from the bottom of the NEO- 50_1 to the 20 ma set point. This setting is measured in either inches or centimeters on the display. SAF1/SAF2/SAF3: Fail-Safe setting for the NEO-50_1. Use the SAF_ settings to determine a fail-safe mode for the current signal. When [SAF1] is set, the current will increase to 22 ma if the signal becomes LOST. When [SAF2] is set, the current will decrease to 4 ma if the signal becomes LOST. When [SAF3] is set, the current will remain constant if the signal becomes LOST. FAST/SLOW: Setting for echo averaging on the NEO-50_1. [FAST] is the typical setting for the NEO-50_1 to operate. [SLOW] is designed to help dampen out effects caused by severe turbulence. In the [FAST] mode, the NEO-50_1 will average 2 signal responses per second and update every second. In the [SLOW] mode, the NEO-50_1 will average signal returns over the preceding 10 seconds. When used with [SAF 1/2/3], the time for the current to default is 30 seconds for [FAST] mode and 2.5 minutes for [SLOW] mode. ALIN: Indicates that the unit is in the Alignment mode. Display will show the return signal strength in db's. Used as an indicator for mechanical alignment of the NEO-50_1 and/or signal attenuation. Typical readings range between 2 and 60 db's. For optimum alignment, first energize the unit and receive a valid return signal. Then select the ALIN mode and adjust the NEO-50_1 until the display value is maximized. ON/OFF: Actual setting for ALIN mode. The ALIN mode must be turned [OFF] when alignment is completed. This mode will not automatically default back to [LEVL]. MAXR: Used as an indication for [MAXR] or maximum range. The MAXR sets the maximum tank height and will filter out all returns greater than this value. (value): Actual MAXR setting. The maximum distance is inches. MINR: Used as an indication for [MINR] or the minimum range. The MINR value is the deadband closest to the transducer face where no signal will be generated. The MINR sets the minimum distance between the liquid and the transducer. (value): Actual MINR setting. The minimum distance is 6.0 inches. MINR MAXR

If LOST appears, please check the following troubleshooting items: 1. Beam cone interference such as the side wall, ladders, seams, rungs or pipes within the NEO-50_1's beam cone. 2. Proper installation such that the NEO-50_1 is installed level and free from interference from the installation fitting or flange. 3. Sufficient power being supplied to the NEO-50_1. The NEO-50_1 requires VDC power with a minimum supply of 25 ma. The NEO-50_1-IS requires VDC power with a minimum supply of 25 ma. 4. Proper programming of the MAXR or MINR function. For best results, set the MAXR function as the distance from the bottom of the tank to the bottom of the transmitter. Also set the MINR distance above the highest level in the tank. Do not set the MINR to less than 6 inches. 5. Make sure that the transmitter is not installed at an angle. Even a 5 degree offset can reduce the signal return strength greatly. Other Hints: Current must change with changes in level. Example: For the illustration below, as level increases, the current output will increase and as the level decreases, the current output will decrease. If the output of the NEO-50_1 is always reading 4 ma or 20 ma, check the input values for the NEO-50_1. EC20 Radius 20 ma EC4 4 ma
